iPhone 16 switches off when charging cable is plugged in and has charging issues

I have an iPhone 16 which is now running iOS 27. It is 14 months old.


When I plug in a charging cable it switches off and I have to start it up again. The only charging unit I can use is the one for my macbook. It does not switch off as many times but the charging only gets to a certain point and stops.


The battery health says it is normal - max capacity 98% , cycle count 205. Made and first used in 2025.


I have tried a whole different set of charging units and none work. I have even tried a wireless charger and that does not work.


I have it booked in for review / repair but the earliest I can get it next Friday afternoon. Any ideas as to what this might be and what I can do would be much appreciated.

I'm sure this is frustrating, but I have no way to gauge the issue for you. Have you tried a Force Restart? Try this, which can fix odd things --> Force restart iPhone - Apple Support


I would also take a flashlight and look in the charging port. If there's any debris or lint in there (very common when phones are kept in pants pockets), use a wooden or plastic toothpick to gently pry any debris from the charging port. Do NOT use canned air.


Third option would be to see if the phone charges either with Qi or MagSafe wireless charging.


If that doesn't help, you'll want to keep your appointment as you could have a hardware issue with the charging port on your iPhone.

Thanks for the advice. I check the port again and it is clear. The forced restart did not make any difference.


I do have a mag safe / wireless charger and it shuts down when that is connected which leads me to believe that it is a hardware rather than software fault.


One thing I have done is used the charging lead from the box and it seems to be ok but the charging is still not working.
